Evaluation of NOx-reduction measures for iron ore rotary kilns

Evaluation of NOx-reduction measures for iron ore rotary kilns

The Grate-Kiln process is employed for sintering and oxidation of iron ore pellets. In this process, a fuel (typically coal) is combusted with a large amount of excess air in a rotary kiln and the high air-to-fuel ratio leads to significant NOx formation. The current paper is an assessment of NOx reduction measures that have been tested in pilot-scale and in full-scale by the Swedish iron ore .

NOx Formation in Rotary Kilns for Iron Ore Pelletization

Sep 25, 2017 · The production of iron ore pellets is often performed in the so-called Grate-Kiln process. The aim of the process is to oxidize the magnetite (Fe3O4) to hematite (Fe2O3) and to sinter the pellets so they can be used in steel manufacturing. The heat required for this is produced by combusting a pulverized fuel in a rotary kiln, forming a suspension flame.
